01
A credible business case.
Model legacy costs, the target operating model and migration investment together. Make the decision with visible assumptions.
Oracle to MariaDB
Move beyond Oracle.
Bring what matters with you.
Preserve business intent, validate application behavior and build a more adaptable data platform. Start with the evidence—not a promise of a one-click switch.
02
A workload-specific path.
Identify Oracle-specific features, PL/SQL dependencies and data semantics before choosing conversion and migration techniques.
03
A controlled transition.
Agree the acceptance criteria, rehearse the sequence and make rollback an explicit decision—not an afterthought.
THE MIGRATION JOURNEY
Replace uncertainty
with decision points.
Each stage produces something your technical, business and risk stakeholders can review.
Discover
Map the workload, dependencies and business case.
Prove
Test compatibility and the highest-risk assumptions.
Engineer
Build the target, convert and validate together.
Rehearse
Practice cutover, reconciliation and rollback.
Operate
Hand over, observe and continuously improve.
A migration timeline is established after discovery. Low downtime, performance improvements and cost reductions are objectives to validate, not blanket guarantees.
COMPATIBILITY, WITHOUT THE SHORTCUTS
Know what carries over.
Know what needs craftsmanship.
MariaDB’s Oracle mode supports a documented subset of Oracle SQL and PL/SQL. The real work is understanding where your application relies on specific behavior.
| Area to assess | What we look for | Evidence to produce |
|---|---|---|
| SQL & data types | Precision, date/time behavior, null handling and query semantics.Representative query results and data-validation tests.||
| PL/SQL & packages | Stored routines, dynamic SQL, exceptions and version-specific support.A conversion backlog and tested remediation patterns.||
| Applications & drivers | Connectors, transactions, connection pools and embedded SQL.Integration and regression-test results.||
| Data movement | Dataset size, change rates, reconciliation and cutover windows.A rehearsed movement plan with recovery checkpoints.||
| Operations & resilience | Monitoring, access, backup, restore and failover behavior.Runbooks and validated recovery procedures.
Compatibility depends on the target version and SQL mode. Consult MariaDB’s official documentation
BUILD YOUR OWN BUSINESS CASE
Better economics.
Start with your numbers.
Explore an illustrative total-cost scenario. Replace every sample value with your own assumptions. This is a planning tool, not a quote or a savings claim.
ILLUSTRATIVE SCENARIO / YOUR INPUTS
$65,000.00
Modeled cost reduction over 3 years.
Current = annual cost × years.
Proposed = annual cost × years + one-time migration.
No discounting, inflation or growth is applied. Costs not entered are not included. Actual results depend on scope, pricing and execution.
QUESTIONS WORTH ASKING
Before you make the move.
Is MariaDB a drop-in replacement for Oracle?
Not for every application. Oracle mode supports a documented subset of Oracle SQL and PL/SQL, and behavior varies by version. A representative proof of concept and application testing are essential.
Can we migrate without downtime?
The acceptable window is a requirement to assess. Data volume, write rate, synchronization options, dependencies and verification steps determine the viable approach. We do not promise zero downtime.
What if some applications cannot move?
The assessment can identify candidates for staged migration, remediation or retention on the source platform. A mixed estate may be more sensible than forcing every workload into a single cutover.
How do we decide whether the migration is ready?
Agree technical and business acceptance criteria, validate data and application outcomes, rehearse recovery, and obtain a named go/no-go decision from the responsible stakeholders.
